Overview
Every IPv4 and IPv6 range mapped to an IANA timezone, with the country alongside it. A range's zone is the one IP Geolocation gives it, the zone of its city, and neighboring ranges in the same zone are merged into one row, so this file holds fewer rows than IP Geolocation. The few ranges with no city, in Bouvet Island (BV) and Heard Island (HM), have no zone and are left out.
